40:50 Solution based deposition technologies

41:00 look into IBM's electrodeposition techniques. It could be transferable to other lines of research.

39:00 how capex varies from vacumm based thechniques to solution-based. It is important when selecting a route with the potential of commercial applications.

[DDDelgado]

36:00 how you have in deposition a distribution curve of chemicals, how important an spectrocopist is to understand the composition of the chemicals beign deposited, this is pretty much a constant in most chemical deposition techniques.

[DDDelgado]

42:30 it is a nice way to help to understand what happens in multinary deposition, why it is difficult to get reproducibility.

Have an issue trying to deposit oleo on to a substrate and the oleo isn’t making to the substrate. Pumping vacuum down to 5e-5 all the AR process works but oleo does not make it to the substrate

Hi when you talked about the defect tolerance of covalent and ionci material, you said both of them were defect-intolerant. did you make a mistake or I had a misunderstanding?
